why did the poet go to the dentist?how could she have avoided it?

Due to ignorance, the narrator neglected her teeth. Then, the narrator suffered from cavities, caps and tooth decay. She had to get filling in her teeth. She had to face drill machines and injections for her decayed teeth. She had to get 2 fillings of amalgum, tortured and helpless on the dentist's chair, gazing in dismay. She could no more enjoy sweets, gums and lollies which she loved so much.
